METHOD AND DEVICE FOR CONTROLLING ELECTRON-BEAM WELDING Russian patent published in 1994 - IPC

Abstract SU 1466129 A3

FIELD: mechanical engineering. SUBSTANCE: steady leakage current and beam current are measured. Average value of beam current is separated and reduced when steady leakage current emerges. Beam current is changed according to difference between average reduced value of beam current and normalized pulses of steady leakage current. Device has steady leakage current and beam current transducers, stabilizer, univibrator, input-output unit, steady leakage current comparator, adder, gun cathode filament voltage unit. High quality of base of the weld is provided by two-step controlling of beam current. EFFECT: improved quality of welds. 2 cl, 2 dwg
